SHUTTLE-OPERATING MECHANISM.

SPECIFICATION forming part of Letters Patent No. 363,724, dated May 24, 1887.

Application filed September 6, 1886. Serial No. 212.808. (No model.)

To all whom it may concern:

Be it known that I, LYNN W. BUoK, of Springfield, in the county of Windsor and State of Vermont, have invented an Improvement in Shuttle-Operating Mechanisms for Looms, of which the following is a full, clear, and exact description.

Hitherto the sweep-stick which connects the picker-stick of a loom to its operating arm or lever has been connected to the pickerstick by means of leather straps or loops, which give a lost motion or permit a certain rebound or freedom of action to the pickerstick, which is essential to the satisfactory operation of the loom; but, owing to the elasticity of the leather and its lack of strength, the said leather connections have-to be frequently renewed, which entails considerable labor and loss of time.

The object of myinvention is to overcome this objection and to make an all-wood or an all-metal connection of the sweep-stick with the picker-stick, and yet retain the freedom of action or rebound of the picker-stick incident to the ordinary leather loop-connections.

To this end my invention consists, principally,of an independent support for the sweepstick, the latter being formed with a slot for the reception of the picker-stick, which permits the picker-stick to move through ashort space independently of the sweep-stick.

The invention also consists of the construction, arrangement, and combination of parts, all'as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

' Figure 1 is a detailed side elevation of a part of a loom, showing the pickerstick, sweepstick, and the arm or stick for supporting the outer end thereof. Fig. 2 is a sectional elewation of the same, taken on theline 00 av of Fig. 1; and Fig. 3 is a sectional plan view 5 taken on the line 3/ y of Fig. l.

A represents the picker-stick, B the sweepstick, and O the independent support for the sweep-stick. These parts are all, by preference, of wood. The picker-stick A and the supporting-stick G are both pivoted upon the gudgeon D of the arm E of the frame of the loom, the same being held upon the gudgeon by a pin or key, a. The sweep-stick B is formed with a slot, F, through which the picker-stick passes, and in which the pickersticl: has a considerable play,so that the pickerstick may have-a considerable motion independent of the sweepstick, as will be understood from Fig. 3. The support 0 is connected to the sweep-stick B by a pivot pin or bolt, b, and it swings freely on the gudgeon D, with the movement of the sweep'stick, and there are several holes, 0, formed in the support 0, so that the sweep-stick may be raised or lowered to regulate the throw of the picker-stick. By this means of supporting the sweep-stick and connecting it with the picker-stick; an all-wood or all-metal connection may be effected, and the picker-stick also given the required freedom of movement or action independent of the sweep-stick which the leather connections permit, and the connection is as durable as the loom and cannot get out of repair; besides, the sweep may be raised or lowered, if desired, by simply placing the pin bin one or the other of the holes 0.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The sweep stick B, in combination with an independent support, 0, said sweep-stick being formed with a slot in which the pickerstick is held, substantially as described.

2. The sweep-stick B, formed with slot F, through which the picker-stick passes, in combination with the picker-stick and the pivotal support 0, the slot F being made larger than the picker-stick to permit independent movement of the picker-stick, substantially as described.

3. The picker-stick A and the sweep-stick B, in combination with the support 0, formed with several holes, a, substantially-as and for the purposes described.

LYNN BUCK.
